Active clinical trials for "Fistula"

Peripheral regional anesthesia induces a sympathectomy-like effect with neurovascular changes causing increased arterial blood flow and venodilatation . Near-infrared spectroscopy (NIRS) can be applied to different kinds of tissue providing oxygen saturation by detecting the absorption and reflection of near-infrared light . The effect on peripheral tissue oxygenation in patients undergoing arteriovenous fistula revision has not yet been examined. We postulate an increase in tissue oxygenation by sympathicolysis caused by peripheral regional anesthesia that might be the reason for beneficial outcome. The aim of our study was to demonstrate the effect of a supraclavicular plexus block in this group of patients.

This observational study aims at assessing the safety and efficacy profiles of mesenchymal stem cell, in different formats (SVF, autologous, allogenic), to treat complex perianal fistula according to the Spanish national Compassionate-use law .

The primary objective of this study is to demonstrate the safety and efficacy of the PHIL® liquid in endovascular treatment of dural arteriovenous fistula.

Depression is a common psychiatric disorder in patients on maintenance hemodialysis (MHD). It may contribute to poor prognosis in a number of ways, including its effect on platelet function. We aimed to investigate the impact and underlying mechanisms of depression on the occurrence of cardio-cerebral vascular events (CCVE) and dysfunction of arteriovenous fistula (DAVF) in MHD patients. In this study, MHD patients were recruited and divided into depression and non-depression groups using the Hamilton Depression Scale (HAMD) in this prospective cohort study. Their clinical and laboratory indicators were collected and the occurrence of CCVE and DAVF were recorded through clinical follow-up, and analyzed, and the differences and possible influencing factors of CCVE and DAVF occurrence were assessed between the two groups of patients.

The incidence of postoperative pancreatic fistula (POPF) after Distal pancreatectomy (DP) remains high. Of the available mitigation strategies, high-quality closure of the pancreatic stump is fundamental. Researchers failed to find a decrease in the incidence of POPF after stapler closure of the pancreatic stump compared with that related to hand-sewn suture in DP. Minimally invasive DP (MDP) is becoming the first choice for patients and surgeons, few studies have evaluated whether stapler closure is superior to hand-sewn suture for stump closure in MDP. Therefore, this retrospective study was aimed at evaluating the effect of stapler versus hand-sewn closure on the incidence of POPF after MDP.

This is an open follow-up clinical trials to evaluate a sustained efficacy and safety of Adipoplus inj. for 10 months (12 months after final dose injection)after Phase II clinical trial.

The goal of this study is to find the best techniques to take non-invasive images of the arteriovenous fistula (AVF) in hemodialysis patients.

This study is a cross-sectional study of 110 Malawian women to compare the ultrasonographic and hormonal characteristics of women and without obstetric fistula. Hypothesis #1: Women with obstetric fistula have a mean cervical length measurement that is at least 10 mm shorter than the mean cervical length measurement of similar women without obstetric fistula. Hypothesis #2: Evaluation of the hormonal and ultrasonographic characteristics of women with obstetric fistula will allow us to assess the cause of amenorrhea in these women.

The purpose of this extension is to investigate and confirm the long-term (6 months) safety and efficacy of the preceding FATT-1 trial [ClinicalTrials.gov identifier: NTC00475410], which studied patients with perianal fistula treated having received adipose-derived adult stem cell (ASC)and/or fibrin glue.

Pancreatic fistula is one of the most serious complication after pancreatoduodenectomy. To reduce pancreatic fistula, many authors recommend pancreatic stent in pancreatojejunostomy. There are two distinct methods of pancreatic stent insertion: internal stent and external stent. There was few studies comparing these methods in preventing pancreatic fistula. Furthermore, its long-term effect was not known enough. The purpose of this study is to determine which is the best method in preventing pancreatic fistula and to investigate its long term clinical outcomes.
